I know how we speak because i am Canadian. I live in Ontario and i've talked to an American a couple times. In Utah they think we say ;

-Sorry (Sarry)
-House (How ess)
-Outside (Owwwtside)

We do say EH, at the end of a sentence BUT NOT ALL THE TIME indicating interest. Like ; three friends are talking in a group and the two leave and walk a way and the one day says ''That dude was an idiot eh?''
